Description
Technical field
The utility model relates to LCD Panel technical field, in particular to a kind of aluminum hull LED screen.
Background technique
LED screen belongs to backlight liquid crystal screen.LED screen with its appearance looks elegant, size is ultra-thin the advantages that receive consumer
Widespread love.LED service life is up to 100,000 hours, even if 10 hours of continuous use daily, can also continuously use 27
Year.Using LED backlight liquid crystal display, energy consumption can be greatly reduced, it is than leading to common CCFL class liquid crystal display power saving 48%.And LED
Environmentally harmful element mercury is not used, it is quite environmentally friendly.
Traditional LED screen heat dissipation performance is not good enough, is increased for a long time using the temperature of liquid crystal display, to be easily reduced liquid
The service life of crystalline substance screen.
Utility model content
The purpose of this utility model is: in view of the above-mentioned problems existing in the prior art, it is good to provide a kind of heat dissipation performance
Aluminum hull LED screen.
The technical solution adopted in the utility model is as follows:
A kind of aluminum hull LED screen, comprising: front casing, screen glass, polarizer, display panel, control circuit board and rear outer
Shell；
There is IC chip in the control circuit board, the rear casing is made of aluminum or aluminum alloy, the control
Circuit board top between the IC chip and rear casing of rear casing one side pass through Heat Conduction Material thermal contact conductance.
In some preferred embodiments, the Heat Conduction Material is heat-conducting silicone grease, and heat-conducting silicone grease is non-conductive, and can
The outer surface of IC chip is come into full contact with, effective contact area is big.
In some preferred embodiments, the Heat Conduction Material is metallic copper, and metallic copper ductility is good and has very
High thermal coefficient, heating conduction are excellent.
In some preferred embodiments, the Heat Conduction Material is metallic silver, and the heating conduction of metallic silver is in common gold
It is very outstanding in category, than the heating conduction of copper also than get well.
In some preferred embodiments, the rear casing is equipped with heat release hole, and setting heat release hole can improve air
Convection current improves the effect of heat dissipation.
The beneficial effects of the utility model are: the aluminum hull LED screen of the utility model, has and compares existing LED screen
Better heat dissipation performance, can use for a long time and temperature does not increase, and improve the service life of LED screen.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment
Below with reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu is fully described by.Many details are explained in the following description in order to fully understand the utility model, but originally
Utility model can also be implemented using other than the one described here other way, and those skilled in the art can not disobey
Similar popularization is done in the case where back the utility model connotation, therefore the utility model is not by the limit of following public specific embodiment
System.
Please refer to the structural schematic diagram of the utility model shown in FIG. 1, the aluminum hull LED screen of the utility model, comprising: preceding
Shell 1, screen glass 2, polarizer 3, display panel 4, control circuit board 5 and rear casing 6.There is integrated electricity in control circuit board 5
Road chip, IC chip are usually main pyrotoxin, and rear casing 6 is made of aluminum or aluminum alloy, in control circuit board 5
Pass through Heat Conduction Material thermal contact conductance between IC chip and rear casing 6 towards 6 one side of rear casing.Heat Conduction Material is preferably led
Hot silicone grease, heat-conducting silicone grease is non-conductive, and can come into full contact with the outer surface of IC chip.It only needs to apply heat-conducting silicone grease
It is layed onto the outer surface of IC chip, while rear casing 6 being designed to and IC chip is in normal mounting to fill
Tap touching.It can reach the purpose to radiate by aluminum hull.In addition to heat-conducting silicone grease, the preferred metallic copper of Heat Conduction Material, to have reached
The purpose of Full connected, metallic copper can be fabricated to plectrum shape.Heat Conduction Material is also an option that metallic silver, metallic silver compare metallic copper
Thermal coefficient it is higher, heat-conducting effect is more preferable.In order to preferably radiate, multiple heat release holes can be set on rear casing 6, setting dissipates
The cross-ventilation in LED screen can be enhanced in hot hole, it is easier to which heat sheds into surrounding air.
Furthermore it is also possible to which fan is arranged in the slot of rear casing, fan can accelerate air to flow, and increase heat dissipation performance.
In the slot of rear casing or temperature sensor can be set in ic core on piece, and detection temperature is transmitted to control by temperature sensor
Device processed, when detecting temperature more than given threshold, controller starts fan work, to play the role of cooling rapidly.
Obviously, described embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.
Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
Every other embodiment, fall within the protection scope of the utility model.
